Abstract
The ridgelines tracing technology based on neighbor-coding and its tracing process are introduced.On the base of it
the fingerprint image post-processing algorithms are improved and the fingerprint minutiae are extracted.By eliminating the possible false minutia and extracting the genuine minutiae on entirely-thinned fingerprint image
the effect of post-processing is perfect.The aim can be achieved that fingerprint minutia correctly extracting and minutia collection exactly founding.It can provide an ideal prepare for next work-fingerprint matching.
